PL259 to PL259 Adapter

The PL-259 to PL-259 Adapter, often referred to as a "double male" or barrel coupler, is designed to connect two devices that both have female SO-239 sockets. This is a common requirement when joining a radio directly to a piece of test equipment like an SWR meter or an antenna tuner without using an intermediate jumper cable, which helps minimize signal loss and saves space.
